Description

Technical Field

[0001] This utility model relates to the field of vibrator technology, specifically to an automatic oil injection device for vibrators. Background Technology

[0002] The vibrator is a crucial component of screening equipment. Based on lubrication methods, vibrators can be categorized into two types: thin oil vibrators and grease vibrators. Grease vibrators suffer from drawbacks such as frequent lubrication, severe axial oil leakage, and difficulty in controlling the amount of grease in the bearing housing. Thin oil vibrators, on the other hand, utilize gear oil circulating within the vibrator housing to achieve bearing lubrication, offering certain advantages. Screening devices generate significant amounts of dust during operation, which accelerates bearing wear in the vibrator, necessitating frequent maintenance. However, existing systems still require periodic maintenance, necessitating machine shutdown and manual disassembly. This not only demands substantial manpower and time but also shortens bearing lifespan and is inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an automatic oil injection device for vibrators. It has a simple structure and is easy to install. It can automatically inject oil into the bearing, thereby increasing the service life of the vibrator and saving a lot of manpower and financial resources. It can effectively solve the problems in the background art.

The rotation of the bearing assembly drives the eccentric excitation device to rotate, which in turn drives the vibration frame and the exciter mounting frame to vibrate. Vibration is achieved in this way. Oil is drawn from the external oil tank into the bearing assembly through an oil injector, thus filling the bearing assembly with lubricating oil. After the oil has been used in the bearing assembly for a period of time, it is discharged through the oil outlet pipe, and new lubricating oil is added.

A pulley 5 is fixed to the upper outer side of the bearing assembly 4, and a pulley 5 is fixed at the middle position of the outer side of the bearing assembly 4. An eccentric vibration device 6 is installed. The vibrator mounting frame 2 includes an edge support frame 21 fixed to the inner side of the vibration frame 1. Mounting support plates 22 are bolted to both the upper and lower surfaces of the edge support frame 21. The centers of the two mounting support plates 22 have mounting through holes corresponding to the bearing assembly 4. The eccentric vibration device 6 includes a support ring 61 fixed to the outer side of the bearing assembly 4. An eccentric block mounting plate 62 is fixed to the upper surface of the support ring 61. A counterweight 63 is fixedly mounted on the eccentric block mounting plate 62. An external drive motor drives a pulley 5 to rotate via a belt. The rotation of the pulley 5 drives the bearing assembly 4 to rotate, which in turn drives the eccentric vibration device 6 to rotate. When the eccentric excitation device 6 rotates, it drives the vibration frame 1 and the exciter mounting frame 2 to vibrate. Vibration is achieved in this way. The bearing assembly 4 includes a shaft 41, and the upper and lower outer sides of the shaft 41 are connected by tapered plates 42. Pressure plates 43 are fixed at both ends of the shaft 41, and the two pressure plates 43 are respectively sealed to the tapered plates 42.

The upper and lower ends of the shaft 41 are provided with T-shaped flow channels that communicate with both ends of the bearing 44. A protective ring is provided on the outer side of the shaft 41. The protective ring allows lubricating oil to pass through the bearing 44 and be discharged from the oil outlet pipe 7. The upper end of the cylinder 45 is connected to a pulley 5. Lubricating oil enters the upper T-shaped flow channel of the shaft 41 from the oil injection pipe 8. The oil inside the T-shaped flow channel flows out from the lower end of the bearing 44. The outflowing lubricating oil enters the oil outlet pipe 7 from the lower end of the T-shaped flow channel of the shaft 41, and is finally discharged from the oil outlet pipe 7. The oil is then drawn from the external oil tank into the bearing assembly 4 through the oil injector 3, thus filling the bearing assembly 4 with lubricating oil.

It can automatically inject oil into the bearing, thereby increasing the service life of the vibrator and saving a lot of manpower and financial resources.

[0014] In use: The external drive motor drives the pulley 5 to rotate via a belt. The rotation of the pulley 5 drives the bearing assembly 4 to rotate. The rotation of the bearing assembly 4 drives the eccentric excitation device 6 to rotate. When the eccentric excitation device 6 rotates, it drives the vibration frame 1 and the exciter mounting frame 2 to vibrate. Vibration is performed in this way. Oil is drawn from the external oil tank into the bearing assembly 4 through the oil injector 3, so that the bearing assembly 4 is filled with lubricating oil. After the oil has been used in the bearing assembly 4 for a period of time, the oil is discharged through the oil outlet pipe 7 and new lubricating oil is flushed in.
